You have just found out that BPC v3.3.* does not support backing up ACL and xattr file permissions. (Sorry)
Several months ago I posted a similar question and Craig suggested that I try BPC v4.0 as it supported ACL and xattr backup.
I did install BPC v4.0.
Sadly, it too has some problem with errors when activating ACL and xattr options.
Apparently the ACL and xattr attributes feature are too new . . . yet.
I ended up finding a way to backup those ACL and xattr directories with a rsync command with the "-A" and "-X" options activated.
What I discovered (and I could be wrong) is that the problem lies in 'rsync-bpc-3.0.9.3' that has been written by Craig Barratt (I think.) I am sure he will have time, at some point in the future, to correct the issue.

Subject: [BackupPC-users] Backuppc and acls / xattrs
Hi everybody.
I'm running a samba server set up to integrate Windows permissions on
ext4 filesystem using the acl_xattr samba module.
Everything is working. Now I would to backup everything on that machine
using an already running backuppc.
The backuppc machine is a Debian 8.2 .
BackupPC package's version is 3.3.0-2.
Rsync version is 3.1.1-3 on both sides (host to backup and backuppc)
If I add --xattrs and --acls to the RSync arguments in the XFer config,
I get the following log:
------------------
full backup started for directory /data/tdp
Running: /usr/bin/ssh -q -x -l root patrick /usr/bin/rsync --server
--sender --numeric-ids --perms --owner --group -D --links --hard-links
--times --block-size=2048 --recursive --one-file-system --ignore-times .
/data/tdp/ --xattrs --acls
Xfer PIDs are now 1931
Got remote protocol 31
Negotiated protocol version 28
Read EOF:
Tried again: got 0 bytes
fileListReceive() failed
Done: 0 files, 0 bytes
Got fatal error during xfer (fileListReceive failed)
Backup aborted (fileListReceive failed)
----------------------
If I run rsync directly on the host "patrick" with a --dry-run, options
seems to be correct.
So why backuppc backups hang if I append those options?
Any suggestion?
